+/**
+ * @defgroup WIZnet_socket_APIs 1. WIZnet socket APIs
+ * @brief WIZnet socket APIs are based on Berkeley socket APIs, thus it has much similar name and interface.
+ * But there is a little bit of difference.
+ * @details
+ * <b> Comparison between WIZnet and Berkeley SOCKET APIs </b>
+ * <table>
+ * <tr> <td><b>API</b></td> <td><b>WIZnet</b></td> <td><b>Berkeley</b></td> </tr>
+ * <tr> <td>socket()</td> <td>O</td> <td>O</td> </tr>
+ * <tr> <td><b>bind()</b></td> <td>X</td> <td>O</td> </tr>
+ * <tr> <td><b>listen()</b></td> <td>O</td> <td>O</td> </tr>
+ * <tr> <td><b>connect()</b></td> <td>O</td> <td>O</td> </tr>
+ * <tr> <td><b>accept()</b></td> <td>X</td> <td>O</td> </tr>

+ * <tr> <td><b>sendto()</b></td> <td>O</td> <td>O</td> </tr>
+ * <tr> <td><b>closesocket()</b></td> <td>O<br>close() & disconnect()</td> <td>O</td> </tr>
+ * </table>
+ * There are @b bind() and @b accept() functions in @b Berkeley SOCKET API but,
+ * not in @b WIZnet SOCKET API. Because socket() of WIZnet is not only creating a SOCKET but also binding a local port number,
+ * and listen() of WIZnet is not only listening to connection request from client but also accepting the connection request. \n
+ * When you program "TCP SERVER" with Berkeley SOCKET API, you can use only one listen port.
+ * When the listen SOCKET accepts a connection request from a client, it keeps listening.
+ * After accepting the connection request, a new SOCKET is created and the new SOCKET is used in communication with the client. \n
+ * Following figure shows network flow diagram by Berkeley SOCKET API.
+ * @image html Berkeley_SOCKET.jpg "<Berkeley SOCKET API>"
+ * But, When you program "TCP SERVER" with WIZnet SOCKET API, you can use as many as 8 listen SOCKET with same port number. \n
+ * Because there's no accept() in WIZnet SOCKET APIs, when the listen SOCKET accepts a connection request from a client,
+ * it is changed in order to communicate with the client.
+ * And the changed SOCKET is not listening any more and is dedicated for communicating with the client. \n
+ * If there're many listen SOCKET with same listen port number and a client requests a connection,
+ * the SOCKET which has the smallest SOCKET number accepts the request and is changed as communication SOCKET. \n
+ * Following figure shows network flow diagram by WIZnet SOCKET API.
